    Abstract:
    INTRODUCTION: Peer-reviewed research helps to advance many aspects of medical and surgical practice. This paper determines the main contributors tos joint arthroplasty research in terms of quantity and quality. METHODS: A search of the Web of Science™ platform was conducted to identify arthroplasty articles published between 2001 and 2016. The number of articles and citations per article were analysed to assess the quantity and quality of research from individual countries. Results were standardised according to the country's populations and Gross Domestic Product (GDP). RESULTS: In total, 43,470 arthroplasty articles were published worldwide from January 2001 through December 2016. There was a 4.5-fold increase in global output during this time period. Twenty-two countries contributed at least 1% to the total number of publications. The United States of America published the most articles (35.40%), followed by England (10.31%) and Germany (10.03%). The USA had the highest absolute number of citations (50,777). Denmark had the highest average citation per item (8.76). When number of articles was normalized to population, Switzerland ranked the highest. When adjusted by GDP, Scotland ranked highest. When standardised according to GDP per capita, the People's Republic of China rated highest. The Journal of Arthroplasty produced the highest number of publications related to arthroplasty with 10.9% of total volume. CONCLUSION: There has been a substantial increase in worldwide publications relating to arthroplasty. The USA has produced the largest volume whilst Denmark has produced the highest quality publications. When output was normalized according to population and GDP, Switzerland and Scotland ranked highest.
